country array

[martin2020]

Hi all

Got a problem that seems simple, but I fail to solve it. Anybody who can help with country array?

Right now the following code is active, which limits the available country to US only, for a certain language/area selection. It works fine. I would now only like to include an additional country (CA) as a choice besides US for the same language/area selection (without changing the language/area selection). If anyone knows the trick pls help.

Existing Code:

if( !function_exists('filter_woocommerce_countries_shipping_countries') ) {
    function filter_woocommerce_countries_shipping_countries( $countries ) { 
        // Filter countries for language
        if( function_exists('icl_get_languages') ) {
            $current_lang = defined( 'ICL_LANGUAGE_CODE' ) ? ICL_LANGUAGE_CODE : 'gl_en';
            if( isset( $countries['US'] ) ) {
                if( $current_lang == 'en' ) {
                    $countries = array( 'US' => $countries['US'] );
                } else {
                    unset( $countries['US'] );
                }
            }
        }
            return $countries; 
    }
}

discovered the solution:

$countries = array( 'US' => $countries['US'],  'CA' => $countries['CA'] );

Another way of doing this that uses some array functions would be:

 

$countries = array_intersect_key($countries, array_fill_keys(array('US','CA'),0));

I would do it this way

$countries = array_intersect_key($countries, ['US'=>null, 'CA'=>null]);

unless I wanted to be super tricky in which I would do it this way

$countries = array_intersect_key($countries, array_flip(['US', 'CA']));

gizmola's way is defiantly more tricky than mine.
